Eco-Toxicology Ecocatalytical Demotechnician

Question: Describe about the Eco-Toxicology for Ecocatalytical Demotechnician. Answer: Jack Vallentyne is considered one of the pioneering scientists of modern century in terms of his significant contributions towards the study of the aquatic ecosystems and empowering the public and the children regarding the various environmental issues that seem to thwart the ecological equilibrium. He is particularly famous as a limnologist and is co-credited with the foundation of a large scientific community named the Aquatic Ecosystem Health and Management Society (AEHMS) embarking in its journey in the year 1989 that is still following on the footsteps of this great visionary. Subsequently a primary journal AEHM, then called as the Journal of Aquatic ecosystem Health, came into circulation from the year 1992. The AEHMS was set up to fulfill the vital objectives of endorsing and adopting the theme of ecosystem health, knowledge enrichment and better understanding concerning the health and management of marine and freshwater ecosystems, investigating and assessing the structure, o peration and performance of the aquatic ecosystems (Munawar, 2013). This prolific personality throughout his eventful career made relentless efforts to environment conservation, restoration and management of aquatic resources and simultaneously conducted mass awareness programs to spread the message of preservation of the natural laws and surroundings. The AEHMS initiated under the patronage of great visionaries like that of Jake Vallentyne has now successfully passed over 20 years and continues to make a difference in the global context through execution of journals, compendium books, symposia and scientific seminars. Jake played distinguished part by virtue of introducing the novel concept of ecosystem approach to research and environmental preservation. Johny Biosphere Project was the brainchild of this philosophy and Jake served to educate the school children through this method. However, he gained maximum popularity through his anti-eutrophication and phosphorus abatement campa igns that has been neatly documented in his book The Algal Bowl (1974). His campaigns were found to be effective as the phosphorus content in the laundry detergents underwent mitigation soon after. Moreover in addition to influencing the general public about the environmental concerns, he influenced the policymaking in a very noteworthy manner, evident in the revision of the Great Lakes Water Quality Agreement (GLWQA) that laid emphasis upon holistic and global outlook measures (Minns, 2013). Jack Vallentyne also performed the Experimental Lakes Area (ELA) program that aimed to evaluate the trophic state and strategies for the control of cultural eutrophication in the lower Great Lakes, experimental eutrophication studies on small lakes to find out the quantitative associations, overall ecological impacts, prevalence of nutrient pollutants and remedial measures. Conduction of comparative analyses with respect to trophic conditions in numerous Canadian lakes to detect the influence of anthropogenic, geologic, climatic and morphometric factors on eutrophication in conjunction to laboratory tests, toxicity studies, bioassays utilizing freshwater organisms were among the other projected objectives of the ELA. Acid rain and the threats of acidification of the lakes were also thoroughly analyzed through ELA. In a nutshell, the ELA provided a snapshot of the water pollution status through nutrient enrichment or eutrophication of the water bodies like that of small natural lakes that provided crucial information pertinent to ecological responses to environmental alterations (Ramsay Walters, 2016). Studies relevant to perceiving the situations encountered due to the ecogenic challenges in the Great Laurentian Basin suggest that identification and rectification of bad fishing and environmental practices can aid to achieve sustainable high value fisheries in addition to the diagnosis of the observed degradation of the aquatic ecosystems to prevent harmful, interacting stresses and also understand and assess the influence of climate warming on the cold blooded fishes (Regier, 2013). Thus the application of the ecosystem approach as proposed by Dr. Vallentyne found reflection in present studies as well. Apart from the aquatic life study, Dr. Vallentyne made his pragmatic mark in the demographic study as well. His insightful opinions regarding the human overpopulation and its consecutive environmental consequences may be retrieved through his writings in the book called Tragedy in Mouse Utopia. His thoughts correlate to the recent population related issues such as immigration and the evaluation of the environmentally sustainable population levels (Hurlbert, 2012). Pertaining to the population study the improvisation of the demotechnic index by Jack Vallentyne may be referred to for comprehensively understanding and estimating the impacts of humans on environment by taking into account both the population numbers as well as the rates of consumption. The changes in the demographic pattern may be attributed to the climate change, food crisis, energy crisis and the growing dearth of fresh water and thereby necessitates the utilization of the demotechnic index to plan and develop ways to address the scenario holistically (Ryerson, 2012). Jack Vallentyne can thus be revered as a true philanthropist and scientist whose pragmatic and time befitting contributions will render profound benefits to mankind in the long term provided his prophetic deductions and recommendations are carried over via worthy legacy.
